Intentionally banning a pick intent champ should be a reportable offense.
I'm sorry, the only thing more dickish than doing that is going something like ADC Veigar. If you ban out my champ I want to play, ESPECIALLY WHEN I'M FIRST PICK AND CAN PICK HIM WITHOUT EFFORT, I'm going to dodge. It becomes crystal clear you are an asshole and probably won't work with your team.
You know, I was hoping that with the new queue some of this shit would have corrected itself, but the longer I play, the more I'm starting to see a resurgence of the same exact crap.l
